A connection hole is formed on a cover of the accommodating box; a cleaning door is arranged on the side wall of the body of the accommodating box; the safety chute consists of a gate arranged in the middle of the safety chute and an electrolyte push rod connected with the gate; the gate divides the safety chute into an upper chute and a lower chute; the electrolyte push rod is connected with the outer side wall of the lower chute; the lower chute is connected with the connection hole on the cover of the accommodating box; and linings made of a refractory material are arranged in the safety chute and the body of the accommodating box. The invention has simple structure, ensures easy operation and is effective protection equipment for the safe production of a grate-kiln.
Description
Technical field
The present invention relates to pelletizing air blast central cooler technical field, relate in particular to a kind of pelletizing air blast central cooler feed hopper safety chute.
Background technology
Pelletizing air blast central cooler is a drying grate--one of key equipment of rotary kiln pelletizing production technology, its feed hopper is to accept through the high temperature pellet behind the rotary kiln baking and the device of the even cloth of high temperature pellet to the chassis, be the steel structure assembly that is welded by steel plate and shaped steel, inwall is lined with refractory material.Under the ordinary production situation, the effect of feed hopper be high temperature pellet behind rotary kiln baking along the radial and axial even distribution of chassis so that can make the high temperature pellet fully, cooling equably, satisfy technological requirement.
If drying grate--certain link of rotary kiln pelletizing system breaks down and causes system normally not move; normally shut down successively by each equipment of technology arrangement order from front to back; to system's end-equipment--after central cooler is discharged the residue pellet; whole system is out of service; fix a breakdown, then system restart.
If system's end-equipment central cooler also breaks down, the material of balance just can not in time be got rid of by system, material will be piled up at central cooler feed hopper place and to anterior equipment gravity flow screen and rotary kiln place in shutoff, the anterior equipment of rotary kiln continues emptying simultaneously, cause the high temperature pellet in rotary kiln, to be piled up, damage the kiln body, make kiln body subscription rate, cause a serious accident.
Summary of the invention
The invention provides a kind of pelletizing air blast central cooler feed hopper safety chute.Its objective is this safe chute is broken down and central cooler can not normally move the time in the grate kiln system, high temperature pellet that also can emptying system middle front part equipment balance, protection gravity flow screen, rotary kiln, thus avoid causing heavy economic losses.
The objective of the invention is to realize by following technical proposals.
Pelletizing air blast central cooler feed hopper safety chute of the present invention, it is characterized in that by the square hole that is located on the air blast central cooler feed hopper lateral wall, the safe chute that is connected of square hole therewith, the bottom of safe chute is connected and is located at the appearance hopper on ground therewith, support safety chute and the support of fixedlying connected with ground, the operating platform that is located on this support is formed, the case lid of described appearance hopper is provided with connecting hole, the sidewall that holds the hopper casing is provided with residue-removing door, described safe chute is by the gate that is located at this safe chute middle part, the Electrohydraulic push rod that is connected of the top of gate is formed therewith, described gate is separated into top chute and bottom chute with safe chute, described Electrohydraulic push rod is fixed on the lateral wall of bottom chute, the end of this Electrohydraulic push rod is connected by hinge with described gate, and described bottom chute is connected with described connecting hole.
Described safe chute and appearance hopper casing are equipped with refractory lining.
The height of the height of described operating platform and Electrohydraulic push rod setting adapts.
The characteristics of pelletizing air blast central cooler feed hopper safety chute of the present invention are: this pelletizing air blast central cooler feed hopper safety chute is the safeguard of grate kiln safety in production, when the grate kiln system breaks down and central cooler can not normally move the time, operating personnel start Electrohydraulic push rod, by the Electrohydraulic push rod starting gate, high temperature pellet in the feed hopper is discharged in the appearance hopper from the safety chute, clears up by residue-removing door after cooling.Preventing that the high temperature pellet from piling up in rotary kiln damages the kiln body, has protected gravity flow screen and rotary kiln, thereby has avoided the generation of major accident.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Further specify the specific embodiment of the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, pelletizing air blast central cooler feed hopper safety chute of the present invention, it is characterized in that by the square hole that is located on air blast central cooler feed hopper 1 lateral wall, the safe chute 2 that is connected of square hole therewith, the bottom of safe therewith chute 2 is connected and is located at the appearance hopper 7 on ground, the support 6 that supports described safe chute 2 and fixedly connected with ground, the operating platform 5 that is located on this support 6 is formed, the case lid of described appearance hopper 7 is provided with connecting hole, the sidewall that holds hopper 7 casings is provided with residue-removing door 8, described safe chute 2 is by the gate 3 that is located at these safe chute 2 middle parts, the Electrohydraulic push rod 4 that is used to handle this gate 3 is formed, described gate 3 is separated into top chute and bottom chute with safe chute 2, described Electrohydraulic push rod 4 is fixed on the lateral wall of bottom chute of chute 2, the end of this Electrohydraulic push rod 4 and described gate 3 are connected by hinge, and described bottom chute is connected with described connecting hole.
Described safe chute 2 and appearance hopper 7 casings are equipped with refractory lining.The service life that prolongs safe chute and hold hopper.The height that the height of described operating platform 5 and Electrohydraulic push rod 4 is provided with adapts, and is convenient to the operation that operating personnel stand in starting gate and closed shutter on the operating platform.
The using method of pelletizing air blast central cooler feed hopper safety chute of the present invention is:
When pelletizing air blast central cooler because during the accident disorderly closedown; accumulate a large amount of high temperature pellets in the feed hopper 1; this moment operating personnel by cat ladder to operating platform 5; open Electrohydraulic push rod 4; by Electrohydraulic push rod 4 starting gates 3; high temperature pellet in the feed hopper is discharged to from safety chute 2 holds in the hopper 7, avoided high temperature pellet shutoff central cooler and pile up to gravity flow screen and rotary kiln place.Slip to and hold the interior high temperature pellet of hopper after cooling, clear up by residue-removing door 8.
After equipment breakdown was got rid of, closed shutter 3 again, return to normal production.
The present invention is simple in structure, is convenient to operation, is effective safeguard of grate kiln safety in production.
